Remarks

• Systematics: Longo et al. (1989) presented sound reasons for the designation of the Neotype. The synonymy of P. deserticola with P. cycliger was based on a comparison of the type material of P. deserticola with the drawings of the P. cycliger by Longo et al., (1989). Pelionella cycliger, currently only known from countries around the Mediterranean, is very similar to P. balteata in having: (i) clusters with only 1 small oral collar tubular duct in the centre, and (ii) 1 size of oral collar tubular duct on dorsum. However, P. cycliger differs from P. balteata in having a much larger number of multilocular pores in each cluster on the dorsum and venter.P. deserticola paratype, adult female: Israel, Wadi Qilt, on Rhus tripartita (Anacardiaceae), deposited in Department of Entomology, The Volcani Center, Bet Dagan, Israel. (Kaydan, 2015) Danzig & Gavrilov-Zimin (2014) used the combination "Pelionella cycliger" before the genus name was made available in Kaydan, 2015 where it was made available in a manner that satisfies the requirements in the Code (ICZN, 1999)
• Structure: Adult female body elongate oval, 1.2-2.5 mm long, 0.7-0.9 mm wide. Antennae 9 segmented. Anterior spiracles larger than posterior spiracles, each 65 µm long, 35 µm wide across atrium. Circulus large. Legs well developed; posterior legs: trochanter + femur 210-250 µm, tibia + tarsus 250-280 µm, claw 21-25 µm long. Both pairs of ostioles present. Cerarii slightly sclerotized, numbering 18 marginal pairs, dorsal absent; anal lobe cerarii each with 2 slender conical setae plus a group of trilocular pores and 2 or 3 spine-like auxiliary setae. (Kaydan, 2015)
• Biology: Leonardi (1908) collected the syntypes from nest of the ant Aphenogaster testaceo-pilosus. Longo et al. (1989) observed this species in association with Crematogaster scutellaris (Oliv.) and with Tapinoma nigerimum (Nyl.). Develops three annual generations on olive in Apulia, Italy. The first instars of the third generation overwinters under the wax cocoon (Porcelli & Pizza, 1995).
• Economic Importance: Porcelli & Pizza (1995) noted that no damage was observed on olive. Mentioned in Tunisia on pomegranate. (Gharbi, 2021)
• General Remarks: Good description and illustration of the adult female given by Leonardi (1920) and by Longo et al. (1989). Redescription and illustration in Kaydan, 2015.
